Rotator cuff related shoulder pain (RCRSP) knowledge is an important contributor to compliance with clinical practice guidelines and providing best practice care. However, there are no validated instruments for measuring health literacy levels among people with RCRSP. This study aimed to design a valid and reliable instrument to measure RCRSP health literacy and use it to evaluate an education intervention for people with RCRSP.
Development of the patient knowledge questionnaire (PKQ-RCRSP) included three phases. Phase 1 was developed based on available literature and input from expert clinicians, researchers and patients. Face validity, pilot testing and readability assessment were also undertaken. In Phase 2, internal consistency and predictive validity were assessed in people with RCRSP and other shoulder pain diagnoses. In Phase 3, RCRSP health literacy was assessed.
Face validity was acceptable and pilot testing identified minor accuracy issues that were corrected. Literacy level was rated as 'difficult to read' which reflects the medical terminology within the questionnaire. Internal consistency was very good and 81% of questions demonstrated acceptable predictive validity. Health literacy was heterogeneous depending on the question with less than 40% of respondents answering correctly for questions related to the indications, process and the known benefits of RCRSP surgery.
The PKQ-RCRSP demonstrated acceptable face validity, predictive validity and reliability (internal consistency) in assessing RCRSP health literacy. Health literacy among our small sample was poor for questions related to surgery for RCRSP.
肩袖相关肩部疼痛（RCRSP）知识对于遵守临床实践指南和提供最佳实践护理至关重要。然而，目前尚无经过验证的工具来测量RCRSP患者的健康素养水平。本研究旨在设计一种有效且可靠的工具来测量RCRSP健康素养，并使用它来评估针对RCRSP患者的教育干预措施。
患者知识问卷（PKQ-RCRSP）的开发包括三个阶段。第一阶段是根据现有文献以及专家临床医生、研究人员和患者的意见制定的。还进行了表面效度、预试验和可读性评估。在第二阶段，对RCRSP患者和其他肩部疼痛诊断患者进行了内部一致性和预测效度评估。在第三阶段，对RCRSP健康素养进行了评估。
表面效度可接受，预试验发现了一些小的准确性问题并进行了纠正。识字水平被评为“难以阅读”，这反映了问卷中的医学术语。内部一致性非常好，81%的问题显示出可接受的预测效度。根据问题的不同，健康素养存在异质性，对于与RCRSP手术的适应症、过程和已知益处相关的问题，回答正确的受访者不到40%。
PKQ-RCRSP在评估RCRSP健康素养方面表现出可接受的表面效度、预测效度和信度（内部一致性）。对于与RCRSP手术相关的问题而言，我们小样本中的健康素养较差。
